WebVarious powerful polyhedral techniques exist to optimize computation intensive programs effectively. Applying these techniques on any non-trivial program is still surprisingly difficult and often not as effective as expected. Most polyhedral tools are limited to a specific programming language. WebPolyhedral optimization asks for the optimal value of a linear function, subject to constraints defined by linear inequalities. The simplex method solves polyhedral optimization problems defined in normal forms. When solving unconstrained optimization problems, the best we can hope to compute are local optima. Polyhedra¶

We support authors whose … WebThe polyhedral model has been successfully used in production compilers. Nevertheless, only a very restricted class of applications can benefit from it. Recent proposals investigated how runtime information could be used to apply polyhedral optimization on applications that do not statically fit the model. In this work, we
